Some information about seraphinite:
Seraphinite (gem quality clinochlore of the chlorite group) is a lovely dark-green stone that changes sparkle and light as you view it from different positions. It comes from mine “Korshunovskaia” which is situated not far from Baikal Lake in Eastern Siberia, Russia. Its hardness is 2 – 2,5 (Moh’s Scale), density 2,6. Chemical formula H8 Mg5 Al2 Si3 O18.
Clinochlore was found and described by the famous Russian mineralogist Nikolai I. Koksharov (1818 – 1892) who was once the director of the Imperial Mineralogical Society. This mineral got its name from the Greek words for inclined and green since its structure is monoclinic and its common color is green (More information about seraphinite).
